v0.2.0-beta.8

• Proposal review shows human conflict reasons and Base / Live / Proposed field
  values, including flow environment variables. Choices have explanations,
  confirmation, a visible chosen state, and persisted undo of the latest choice.

• Proposals with no net deployment change clearly say nothing changes and hide
  approval and security notes.

• Consolidate review notes with a count and separate security from
  configuration; omit duplicate comparisons and unchanged editor diffs. Re-check
  shows progress and a result toast. Pending totals match the badge, including
  conflicts.

• Improve light-theme readability, settings width, sticky navigation clearance,
  sign-in footer visibility and stable sign-in button colors; errors use alerts.

• Reject invalid TTL settings with a minimum of 1; keep invalid input visible
  and never report it saved. Investigate the NR4 Active link (box-only
  findings).

• Merge disjoint fields on the same node and tab, including env entries by
  unique name and credentials by key. Conflict choices preserve independent
  changes from both sides and retain secret safeguards and warnings.

• Keep peer proposals mergeable after approval of a different field on the same
  node.

• Report actual changed fields in outbound_node_changed warnings.

• Expose baseRev and rename the informational revision flag to
  baseRevChanged; use rebase.state and rebase.rev to assess the checked
  merge.

• Add nodeId + choice to MCP/REST proposal resolution and clarify that
  replacement operations apply to the flow snapshot at expectedRev.

• Allow full admins to withdraw proposals after token loss, with recovery
  authority and original ownership in the audit log. Other tokens remain
  blocked.
